Hi,
I have a situation where I have created a GEF context menu class similar
to the GEF examples and added some actions like cut,copy,paste, delete,
align etc. Some other group that is using my code wants to use the
context menu, but they have their own cut and paste actions that they
wish to use. They have action delegate classes for these actions. But
when they contribute via plugin.xml, they get two cut entries and two
paste entries in the context menu.
My question is, is there a way that we can use the GEF context menu but
just replace or override a couple of actions on the menu?
thanks!

This is probly a bad idea, but maybe after you have instantiated all the
GEF stuff, get the corresponding action registry and replace the actions
you are overriding with your own ( but use the same registry key ). That
way your action is called instead of the one in the action registry by
default.

Thanks for your response. But I still don't understand how to do this.
The other team writes the new actions, but uses our context menu which
is the GEF Contextmenu.He wants to contribute his actions so that he can
replace just one or two of the actions on the context menu with his actions.
I saw that there is an overrideActionId parameter in the extension point
for popup menus. Would that work in such a situation?
thanks!

I've never done anything like this, so I can't say anything for sure. But
if you add two actions with the same ID, won't the second one override the
first one? Alternatively, something like a retarget action might solve your
problem. A retarget action delegates to some other action based on the
current selection. Your retarget action could switch between your cut
action and the one contributed by your clients. BTW, which cut/paste action
is executed when you use the menu bar?

First validate that I understand what you want.
YOU have a menu with actions in it that you have created or that are
under your control. The Other group wants to, when they plugin, take
over control of your actions.
If this is the case, you need to create an extension point for your
plugin, and they can by use of that extension point, tell your plugin of
their desire to override your methods. Your plugin can then pass
control to them for those methods.

Hi! You have understood it correctly. Except, the other group only wants
to replace one or two of the actions. So for instance, I have a GEF
context menu for my graphical editor, and it has my actions for cut and
paste, along with several other actions, including the alignment actions.
Now, the other group wants to use all of my actions, except for cut and
paste. What they want is to somehow when they click on cut, it should be
their cut action that gets triggered and not ours. Does that make sense?
Do I still need to have an extension point for my context menu? Is there
any other way to achieve this?
thanks!

Yes you need an extension point. Your plugin must create the ability
for them to override whatever you want them to be able to override.
They can only do to/with your plugin what you let them.
When you show your context menu, you should check the implementers of
your extension point. If there are any, call a method that gives them
the opportunity to fill out the menu. Perhaps a visitor. Its not too
hard to do.
